Abstract

Aim: To determine the mean distance between Infraorbital foramen (IOF) and infraorbital margin (IOM) on both sides of dried human skulls, which is useful while performing surgical procedures in relation to infraorbital foramen and giving regional nerve blocks. Materials and method: 100 adult skulls of both sex (66 males and 34 females) irrespective of age were used for the study. The shape, orientation, location in relation with teeth and presence of accessory foramina were observed by direct inspection. The distance between infraorbital foramen and infraorbital margin was measured by using the digital vernier calipers. Results: The majority of IOF were oval shaped in male skulls (54.7%) and on left side (52.8%). The majority of IOF were directed inferomedially (65.8% in males; 67.8% in females). The majority of IOF were vertically oriented to 2nd premolar teeth (43% in both sexes and on both sides). The mean distance of infra orbital foramen from the infra orbital margin was 7.39▒1.63mm. Accessory foramen were noticed in 4% skulls. Conclusion: The results of our study may be helpful during surgical procedures in relation to infra orbital foramen and giving regional nerve block.
